Abstract
Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density on Rasbora aprotaenia seeds are necessary to support the availability of seeds in fish farming. Cultivation needed becauseincreased fishing of Paray fish threatens its sustainability. Before starting fish cultivation, it is necessary to determine the optimal stocking density. The determination of fish stocking density will affect the fish harvest, in the wrong stocking density makes the results of the cultivation became bad, this study aims to spread this problem. This study was conducted on December 2024 to January2025, at the Aquaculture Laboratory, Fisheries Science Study Program, Faculty of Agriculture, Sultan Ageng Tirtayasa University. The treatments consisted of 2, 4,6 fish/L. The fish used were 180 Rasbora aprotaenia, measuring 2.33 ± 0.05cm/fish. The maintenance aquarium measuring 30 x 30 x 30 cm3as many as 9 pieces was then filled with 5 liters of water and the fish were spread to each treatment. feeding technique using 3% of biomass weight and fengli 0 type pellets. Food is given twice a day. water quality measurements include pH, temperature, DO, and ammonia. The parameters measured are survival rate, absolute weight growth, spesific growth rate, feed conversion ratio, absolute length growth, coefficient of diversity and water quality. The results of the survival rate (p>0.05) were not significantly different, absolute weight growth(p>0.05) was not significantly different, spesific growth rate had a real effect (p<0.05), feed conversion ratio had a real effect (p<0.05), absolute length had areal effect (p<0.05), the diversity coefficient of treatment A and B was included inthe homogeneous data criteria, followed by treatment C included in the heterogeneous criteria. The water quality of each treatment is included in the good category that fish can tolerate and still supports fish survival. Different stocking densities significantly affected absolute length growth, specific growth rate, and feed conversion ratio (p<0.05). Meanwhile, although survival rate and absolute weight growth were influenced, the differences were not statistically significant(p>0.05).

| Additional Information: | Upaya yang untuk membudidayakan R. aprotaenia secara intensif ikan belum ada. ikan paray banyak ditangkap secara langsung dari alam. Pembudidayaan diperlukan karena peningkatan penangkapan ikan paray mengancam kelestariannya. Sebelum mulai budidaya ikan perlu penentuan padat tebar yangoptimum. Penentun padat tebar ikan berpengaruh dalam hasil panen ikan, dalam padat tebar yang salah memperburuk hasil budidaya tersebut, penelitian inibertujuan untuk mengevaluasi masalah tersebut.Penelitian ini dilaksanakan pada bulan Desember 2024 sampai Januari 2025, diLaboratorium Budidaya Perairan, Program Studi Ilmu Perikanan, Fakultas Pertanian, Universitas Sultan Ageng Tirtayasa. Perlakuan terdiri dari 2 ekor/L, 4ekor/L, dan 6 ekor/L. Ikan yang digunakan adalah benih ikan paray R. aprotaenia sebanyak 180 ekor ukuran 2,33±0,05 cm/ekor. Akuarium pemeliharaan berukuran30 x 30 x 30 cm3 sebanyak 9 buah kemudian diisi air sebanyak 5 liter dan ikan ditebar ke tiap perlakuan. Pemeliharaan ikan dilakukan . pemberian pakan dengan feeding rate 3% dan pelet jenis Fengli 0. Makanan diberikan dua kali sehari.pengukuran kualitas air meliputi pH, suhu, DO, dan amonia. Parameter yang diamati pertumbuhan kelangsungan hidup, bobot mutlak, laju pertumbuhan harian, konversi pakan, pertumbuhan panjang mutlak, pertumbuhan faktor kondisi dan kualitas air. Hasil penelitian kelangsungan hidup (p>0,05) tidak berbeda nyata, pertumbuhan bobot mutlak (p>0,05) tidak berbeda nyata, laju pertumbuhan harian berpengaruhnyata (p<0,05), rasio konversi pakan berpengaruh nyata (p<0,05), panjang mutlak berpengaruh nyata (p<0,05), koefisien keragaman perlakuan A dan B termasuk dalam kriteria data homogen, dilanjutkan perlakuan C termasuk dalam kriteria heterogen. Kualitas air tiap perlakuan termasuk dalam kategori baik yang dapat diterima ikan dan masih mendukung kelangsungan hidup ikan.Padat penebaran yang bebeda berpengaruh terhadap pertumbuhan panjang mutlak, laju pertumbuhan harian, dan rasio konversi pakan, secara statistik berbeda nyata(p<0,05). Sementara pada persentase kelangsungan hidup dan pertumbuhan bobot mutlak memberikan pengaruh, namun secara statistik tidak berbeda nyata secara (p>0,05). | |||||||||
